The dual planets were intertwined in each other's tragic destiny, dancing an eternal rondo around a pitch-black great sun.

In the beginning, one of the planets gave rise to humans. These people looked down, and named the land below "Izumo." These people looked up, and named the world above "Takamagahara."

One day uninscribed in the annals, the Yaoyorozu-no-kami descended from Takamagahara. These demonic beasts named Kami overturned the skies, burned the rivers and oceans, and shattered the land — People realized in horror that it was not an invasion for rulership, dominance, or plunder. The evil Kami came only to kill.

As the planet stood on the brink of death, Izumo embarked on a Kami-slaying journey, exhausting the might of the entire country to slay the calamity "Sovereign of Revelation" and forging the very first Edict Edge using its bestial body.
